9 Capture - Refile - Archive

An important part of any organization system is the ability to quickly
capture new ideas and tasks, and to associate reference material with them.
Org does this using a process called capture. It also can store files
related to a task (attachments) in a special directory. Once in the
system, tasks and projects need to be moved around. Moving completed project
trees to an archive file keeps the system compact and fast.
